Do You Need a Static IP with Your Leased Line? A Quick Business Guide

When shopping for a business leased line, we understand that you’ll likely be focused on speed, reliability, and uptime—but there’s another essential detail to consider: your IP address... Specifically, whether you need a static IP.

So what exactly is a static IP address, why does it matter, and is it included in your leased line package?

Let’s take a look at what they’re used for, how they differ from dynamic IPs, and what to ask your provider before you sign the dotted line.

🌐 What Is a Static IP Address?

An IP address is a unique string of numbers assigned to every device or network connected to the internet, and there are two main types:

• Dynamic IP which changes periodically and is automatically assigned by your ISP (internet service provider)
• and a Static IP which remains fixed and never changes, offering a consistent point of access to your business network

🔒 Why Might Your Business Need a Static IP?

While dynamic IPs are fine for everyday web browsing, static IPs are essential for many business-critical functions.

✅ Common use cases for a static IP:

Remote access and VPNs

This will allow your employees to securely log into your network from anywhere, without IP restrictions constantly changing.

Hosting servers

If your business hosts a website, file server, or mail server on-site, a static IP will bring you consistent accessibility.

VoIP phone systems

Some VoIP services require a static IP for reliable call routing and connectivity.

CCTV and remote monitoring

Where you can access cameras or security systems remotely without needing to track changing IPs.

DNS and email hosting

you can host your own domain and services in-house, with reliable IP-based configurations.

🏢 Do Leased Lines in the UK Come with Static IPs?

Yes—most UK leased line providers include at least one static IP address as standard, with the option to request additional IPs (usually at a small extra cost).

Here’s what you can typically expect:

💷 Are There Extra Costs for Static IPs?

Usually, one static IP is included at no extra charge with most leased line contracts, but keep in mind that:

• IP blocks (e.g. 4, 8, or 16 IPs) may incur a monthly fee (£5–£20+ depending on provider)
• Some providers charge for IP configuration or management if not done at setup
• If you request static IPs after installation, setup may be more complex

⚠️ What to Ask Your Provider

Before finalising your leased line order, ask the following:

• How many static IP addresses are included?
• Can I request additional IPs, and at what cost?
• Are IP addresses IPv4 or IPv6 (or both)?
• Will I have control over DNS and reverse DNS settings?
• Can I configure firewalls and access rules?

🛠️ Do You Always Need a Static IP?

Not every small business will need one – take for example if you’re using your leased line simply for fast browsing, email, and general cloud access, a static IP may not be critical. However, if you:

• Use remote working solutions
• Host internal systems or websites
• Depend on stable connectivity for VoIP or CCTV —then a static IP is strongly recommended.

✅We Think It’s A Small Feature with Big Impact

While it might seem like a small detail, we do think that having a static IP with your leased line can significantly improve the way your business runs—especially if you use modern cloud tools, security systems, or in-house hosting.

Most UK providers include it by default, but it’s always worth checking the fine print and confirming what’s included in your quote!
